CHARLES D. MOSHER, OF NEW YORK, N. Y.

STEAM-SEPARATO R.

SPECIFICATION forming part of Letters Patent No. 472,308, dated April 5, 1892. Application filed July 13, 1891- Sen'al No. 399,282. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES D. MOSHER, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Steam-Separators, of which the following is a specification.

This invention relates to a separator forming a portion of a steam pipe or conduit through which steam passes from the boiler and constructed to separate from the steam any entrained water carried by it, so that the steam when delivered to the engine will be devoid of entrained or visible water. Heretofore in appliances of this class the Water has been accumulated in a receptacle or settling chamber or basin communicating with the conduit, but so arranged that the steam has more or less free access to the Water accumulated in said receptacle, so that liability always exists of the steam agitating the accumulated water and converting a portion of it into spray and carrying the spray to the engine.

My invention has for its object to provide a separator in which the entrained water, after entering the receptacle provided for it, shall be beyond the influence of the steam, so that there will be no liability of the agitation or spraying of the entrained water by the steam and the conveyance thereof to the en- @1116.

a In Patent No. 454,984, granted to me June 30, 1891, I show a steam-flue located within a boiler and connected at one end with the pipe or conduit for conveying the steam from the boiler, said flue having a diaphragm of a construction somewhat similar to what is shown in Fig. 1 ofthis specification. In such patent the flue containing the helical diaphragm or partition is open at one end inside the boiler, and, furthermore, the receptacle or trap for the entrained water is open at the bottom; but since the steam-pressure within the boiler is equal inside and outside of said fiue the steam passing through the latter will not escape, except at the desired outlet, nor force the water out of the receptacle, although the latter is open. To adapt a separator of such general construction to use in a steam-conduit outside of a boiler is the particular obj ect of my present invention, which therefore consists in a separator comprising in its construction a section of a steam pipe or conduit having at its ends means for attachment to adjoining sections of the conduit, a helical partition or diaphragm extending longitudinally through the said section and adapted to give a gyrating motion to the steam passing therethrough, a closed reservoir or receptacle below said section for the entrained Water, and an outlet in the lower portion of the section connecting the latter with the said receptacle, so that the entrained water which is thrown outwardly against the Wall of the receptacle by centrifugal action caused by the gyrating motion of the steam will pass through said outlet into the receptacle, the outlet being so formed and arranged that it divides the entrained waterfrom the steam and guides the water into the receptacle Without permitting the steam to enter the latter, all of Which I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a longitudinal section of a separator embody ing my invention. Fig. 2 represents a transverse section on line 2 2 of Fig. 1. Fig. 3 represents a longitudinal section of a modification. Figs. 4, 5, and 6 represent transverse sections of other modifications. Fig. 7 represents a transverse section of another modification.

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention I provide a casing a, which is open at both ends and constitutes a section of a steam pipe or conduit, said section being provided at its ends with suitable means for attachment to other sections of the steam pipe or conduit. The attaching means may be flanges a a, provided with suitable bolt-holes, as shown in Figs. 1 and 2, or screw-threads a a formed on the end portions of the section, asshown in Fig. 3, for the purpose of engaging with corresponding screw-threads on the adjoining sections, or any other suitable contrivances whereby the section a may be detachably secured at its ends to the adjoining ends of other sections belonging to the line of pipe or conduit.

12 represents a helical partition or diaphragm extending longitudinally through the section a, and formed preferably like the blade of an anger, said partition being of such width that it extends across the interior of the section a and subdivides said section into two helical flues. It will be seen that the helical partition gives the steam passing through the section a. a gyrating motion, which causes the free water carried by the steam to fly outwardly by centrifugal action against the inner surface or wall of the section a.

0 represents a reservoir or receptacle below the section a, and preferably cast in the same piece therewith. Said reservoir communicates with the interior of the section a through an outlet-passage (1, extending along the lower portion of the section a; Said outlet is narrow and preferably extends the entire length of the receptacle 0. The outlet is formed between two lips or flanges e e, which may con -stitute portions of the inner wall of the section a, and are separated from each other by a space forming the outlet. The section a is of scroll or spiral form in cross-section, so that one of the lips e overlaps the other, as shown, the lower lip being a continuation of the eccentric side or portion of the scroll.

The gyrating motion of the steam is in the direction indicated by the arrow in Fig. 2, so that the water dashed against the wall of the section a is carried in the same direction until it reaches the opening cl, where it is divided from the steam, the water passing into the receptacle 0, while the steam passes onward through the casing to. There is there fore no liability of the agitation or spraying of the entrained water accumulated in the reservoir 0 by the steam.

My invention is not limited to the spiral form in cross-section, as the inner surface of the section a may be practically circular in cross-section, the outlet (Z being in this case substantially tangential with the said inner surface, as shown in Fig.5. I prefer the form shown in Figs. 2 and a, however, for the rea sons above stated.

The lips or flanges e 6, between which the outlet cl is formed, may be integral with the section a and reservoir 0, as shown in Figs. 2 and 5, or they may be the edges of a scroll s, of sheet metal, inserted in the section a and riveted or otherwise secured to the upper portion of the latter at r, as shown in Fig. l, the edges of said scroll overlapping and being separated by a space constituting the outlet cl.

In Fig. 6 I show two flanges it, of sheet metal, riveted at a a to the section a, the

outer edges of said flanges overlapping and forming the opening (Z.

It will be observed that when the section a is provided at its ends with the flanges for attachment to other sections the reservoir 0 is located between said flanges and does not add to the bulk of the section.

The water-receptacle may be connected with a trap having suitable means for disposing of the entrained water. As there are many well-known traps that will be suitable for this purpose, a description of the construction of any particular trap is not necessary.

In Fig. 7 I show a modification in which the spiral diaphragm is incased in a cylinder n of wire-gauze, the latter being attached to the interior of the casing or section a. The openings in the wire-gauze permit the passage of the entrained water to the water-receptacle, which in this case is separated from the steam-passage only by the wire-gauze cylinder. It will be seen that the wire-gauze prevents the steam from acting on the water accumulated in the receptacle in such manner as to return any of it to the steam-passage. It will also be seen that each of the constructions above described has a steam-passage, a water-receptacle located below said passage, and a partition between the steam-passage and receptacle, the said partition being the overlapping lips or flanges e e in the construction shown in Figs. 1, 2, 3, 4, 5, and 6 and the wire-gauze cylinder shown in Fig. 7. In each case the said partition permits the entrained water to pass freely to the waterreceptacle and prevents the steam from circnlating in said receptacle to such an extent as to break up the water therein and carryit on through the steam-passage.

I claim- 1. The improved steam-separator hereinbefore described, comprising in its construction a section of a steam pipe or conduit provided at its ends with means for attachment to other sections of the conduit and having alongi tudinal helical diaphragm or partition formed to impart a gyrating movement to steam pass ing through said section, and thereby throw the entrained water carried by said steam outwardly by centrifugal action against the wall of the section, and a longitudinal outlet at its lower portion for the escape of the entrained water, and a closed receptacle for the escaping waterbelow said outlet, as set forth.

2. In a steam-separator, the casing constituting a section of a steam pipe or conduit, formed at its ends for attachment to other sections and provided at its lower portion with a closed water'receptacle and above said receptacle with a longitudinal outlet formed between two lips or flanges, one overlapping the other, combined with a helical diaphragm or partition extending longitudinally through said section and subdividing the latter into two helical lines, each of which communicates with said outlet, as set forth.

3. In a steam-separator, the combination of a casing constituting a section of a steam pipe or conduit, having at its ends means for attachment to other sections, a helical partition or diaphragm extending through said section, and a closed receptacle for entrained water extending lengthwise of said section along the lower side thereof, the interior surface of the section having a spiral or scroll form in cross-section, the overlapping edges of said surface being at the lower portion of trained water from the steam-passage to the Water-receptacle, said partition being formed 15 to prevent the steam from breaking up and carrying onward the water that enters the said receptacle, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of 20 two subscribing Witnesses, this 3d day of July,
